Description/Abstract | Explains how increasing natural gas costs provided the incentive to install a mechanical vapor recompression unit that accomodates variations in production rates and provides for plant expansion.^The evaporator can concentrate uranyl nitrate solution with much more energy efficiency.^Uranyl nitrate solution is purified in the solvent extraction portion of the process, concentrated by evaporation, and then introduced into boildown, where all remaining free water is removed.^Benefits of a vapor recompression evaporation system over a single-effect evaporator include not only energy cost savings, but a reduction of about 50% on the plant steam demand and 35% on the heat and pumping load of the plant cooling tower.^Material to be evaporated must be thoroughly evaluated to determine that the physical properties are within the economic limits of a vapor recompression system.^Available energy sources and other plant needs must also be considered.^Concludes that comparison of the installed and operating costs reveals that the multi-effect system cannot compete economically with mechanical vapor recompression, unless the former can also meet unique thermal needs of the plant other than evaporation. |
